Each happy farm animal "sounds off" in its own voice when its animal puzzle piece is placed correctly in this eight-piece wooden peg puzzle! Your child will enjoy hearing all eight sounds and looking at the full-color, matching pictures under the pieces, while developing matching and listening skills with this captivating multisensory puzzle. (TIP: Puzzle has light-activated sensors; for best results, expose the sensor by removing a piece in a brightly lit room, then make the sound play by replacing the piece in the board.)
